GURPS Vehicles had some options that you needed to do a little calculus for, iirc. To be fair, that was an extremely optional add-on, and the calculations were done as part of designing your custom vehicle, not in play!
Their speed/range penalty calculation is also logarithmic I think, but nobody actually calculates that - you just look up the adjustments on the table, which is reprinted all over the place (rulebooks, character sheets,GM screens…)
Gotta use trigonometry to accurately calculate the distance to flying enemies
Is there any rpg where you need to do so? May be Fatal?
